Site Selection
The following criteria should be considered when selecting a site to install the switch:
•
Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow
to the front and back of the switch. The ambient temperature should not go below 0° or exceed
40°C.
Important: To prevent the switch from overheating, do not operate it in an area where the
ambient temperature exceeds 40°C (104°F).
Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
•
Airflow Orientation: Determine airflow direction of the fan modules on the rear panel and the
power supply modules on the front panel. Fan and power supply module handles indicate airflow
direction:
•
Blue Handle: Air Inlet module
•
Red Handle: Air Exit module
displays fan and power supply module locations on the device. Base the switch
orientation on the airflow direction of the modules to assure the air inlet is always oriented toward the
cool aisle.
•
Air Exit modules: orient the rear panel toward the hot aisle.
•
Air Inlet modules: orient the rear panel toward the cool aisle.
If the airflow direction is not compatible with the installation site, contact your sales representative to
obtain modules that circulate air in the opposite direction.
•
Rack Space: Install the switch in a 19" rack or cabinet. The switch height is 1 RU. The accessory kit
provides mounting brackets for two-post and four-post racks.
When mounting the switch in a partially filled rack, load the rack from bottom to top, with the heaviest
equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.
•
Power Requirements: Power requirements vary by switch and power supply model. Refer to
Table 4: Switch Specifications (Power Input)
Table 5: Switch Specifications (Power Draw)
for
information regarding your specific system.
